Cuatro contenedores idénticos tienen la misma cantidad de gas hidrógeno a la misma temperatura inicial. Los recipientes también
cuentan con un émbolo móvil que no permite que el hidrógeno escape.
Cada muestra de gas sigue un proceso distinto como se describe a
continuación: Contenedor 1: 470J de calor salen del gas y se hace un
trabajo de 320J sobre él. Contenedor 2:470J de calor salen del gas y
este realiza 320J de trabajo. Contenedor 3:470J de calor entran al gas y
se hace un trabajo de 320J sobre él. Contenedor 4: 470J de calor entran
al gas y este realiza 320J de trabajo. Determina el cambio en energia
interna para cada uno de los sistemas descritos.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
